She earned a whopping $458 million from touring, along with $304 million in acting gigs (huh?) for films like The Nutty Professor, $206 million in album sales, and $81 million in sponsorships.

Not many entertainment figures are billionaires, although Steven Spielberg, Oprah Winfrey, and J.K. Rowling are among the small group.

What's even crazier is the fact that Janet's husband is a billionaire in his own right as well, having made money with investments in the Middle East. So if you ever going out to dinner with them, you can let them pick up the check.

We must admit, we're kinda shocked that Janet has this much more money than Madonna. And how has Janet made so much dough from films?
